Demon Spore



An action horror rogue-lite where you need to improvise a plan to escape from a constantly evolving life form. Fight against a mass of ever expanding tentacles that is spreading not only to infest the space you’re in, but the entire facility. Use the lab to your advantage and improvise a desperate escape plan before this deadly organism spreads out of control.


Deep inside a genetic research laboratory, scientists are racing to solve the problem of feeding an ever growing population. Using gene editing procedures they are overstepping ethical boundaries to breed the fastest growing livestock on the planet. But after an experiment is mysteriously interfered with it gives birth to a viral mass of cells that is spreading out of control and evolving into a creature from hell.

As a scientist trapped inside with a few survivors, you must use your scientific experience to learn how the organism behaves, find its weaknesses and fight your way to safety.


An abomination of flesh and tentacles with a taste for organic matter, constantly evolving and adapting, infecting everything - even your fellow scientist can turn against you. Escape each floor before the growth mutates into something even more horrific.

Every room has new surprises and tough choices - risk a dangerous encounter to grab new gear? Save a scientist or cut your losses and run to the exit? Rescue and protect lab personnel so they can create new technology to improve your chances of survival.

Use any lab tools you can find to slice through the creature’s tentacles, target its weak spots and stunt the growth. Cobble together experimental weaponry and repurpose lab equipment to improvise your way to safety in an ever changing environment.

Each room has different threats and different rewards, choose your path wisely to stay one step ahead of the creature. Every time you play you face a different layout but will learn more of the secrets of the lab and how to use them to your advantage to outsmart your enemy.

About Developer

Hi! I’m Ed. I’ve been making games for 20 years, mostly as a designer. I’ve worked on a lot of action games like Bulletstorm, Timeshift, Counterspy etc. as well some horror games like Call of Cthulhu: Dark Corners of the Earth. I was also working on a Star Wars game at Lucasarts until Disney bought the company and decided to cancel all internal projects. I was tired of being at the mercy of big corporations so I decided to leave AAA console development and make my way into indie games. A few years later I launched Hang Line and this was successful enough to allow me to start my passion project - Demon Spore.
